Detailed Implementation

[0023] Please see Figures 1 to 3 This is a schematic diagram of a rebar weight deviation detection device provided by this utility model. The rebar weight deviation detection device includes: a detection platform 10, a length detection component 20 disposed on the detection platform 10, and a weighing component 30. It should be noted that during detection, the original rebar to be tested needs to be pre-cut into multiple segments of appropriate length. Then, the length of the segments is measured by the length detection component 20, and the weight of the segments is obtained by the weighing component 30, thereby determining whether the quality of each segment of the rebar meets the standard. This rebar weight deviation detection device also includes other functional components and specific structures, such as electrical connection components, data storage modules, and calculation modules, which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0024] The testing platform 10 is the installation carrier. The testing platform 10 is installed flat on the flattening machine. The testing platform 10 has an installation cavity inside, and the power supply module, data storage module, and calculation module are installed in the installation cavity. A display screen is provided on one side of the testing platform 10 to display values ​​or directly obtain calculated values. These are all existing technologies and will not be described in detail here.

[0025] The length detection component 20 includes a fixed clamping seat 21 disposed on the detection platform 10. The fixed clamping seat 21 has a strip-shaped structure and is arranged along the length direction of the detection platform 10. A fixed stop 22 is provided at one end of the fixed clamping seat 21. The fixed stop 22 is disposed at the end of the fixed clamping seat 21 and is vertically arranged. A movable clamping seat 23 is axially elastically connected to the end of the fixed clamping seat 21 away from the fixed stop 22. A movable stop 24 is provided on the movable clamping seat 23. The movable stop 24 is disposed at the end of the movable clamping seat 23 away from the fixed clamping seat 21. The movable stop 24 is vertically arranged corresponding to the fixed stop 22. Specifically, a mounting groove 26 is provided at one end of the movable clamping seat 23 for the axial guidance of the fixed clamping seat 21. The movable stop 24 and the fixed stop 22 are connected in the mounting groove 26 by a spring 27. The elastic potential energy of the spring 27 forces the movable stop 24 to move towards the fixed stop 22, thereby achieving clamping at both ends of the clamping seat. It is conceivable that the minimum distance between the fixed stop 22 and the movable stop 24 is less than the length of the segmented steel bar, so that the two ends of the segmented steel bar can be clamped by abutting against the fixed stop 22 and the movable stop 24 respectively.

[0026] In this embodiment, both the fixed clamping seat 21 and the movable clamping seat 23 are equipped with abutment rollers 25. The segmented reinforcing bars need to be placed horizontally between the fixed stop block 22 and the movable stop block 24. The two abutment rollers 25 serve as support points for the segmented reinforcing bars. At the same time, the segmented reinforcing bars are adjusted by rolling during clamping, which reduces friction and increases detection efficiency. The abutment rollers 25 have a recessed rolling groove 251 in the middle, which is suitable for detecting reinforcing bars of various sizes. The rolling groove 251 restricts the circumferential outer wall of the segmented reinforcing bars and prevents the segmented reinforcing bars from radially shifting.

[0027] In this embodiment, two axially protruding circumferential clamping blocks 241 are provided on both sides of the movable stop 24, with the axial inward direction facing the fixed stop 22. By adjusting the distance between the two circumferential clamping blocks 241 to approach the outer wall of the end of the segmented rebar, the segmented rebar can be pre-pressed against the movable stop 24 and force applied to push the movable stop 24. Specifically, the circumferential clamping blocks 241 are sleeved on the screw rod. By screwing the screw rod into both sides of the end of the movable stop 24, the circumferential clamping blocks 241 can be adjusted to move along the width direction of the movable clamping seat 23 to adapt to the end size of the segmented rebar. The setting height of the circumferential clamping blocks 241 corresponds to the height of the roll groove 251.

[0028] In other embodiments, drive cylinders can be provided on both sides of the movable stop 24 to drive the circumferential clamping block 241 and provide circumferential positioning when the segmented steel bar abuts against the movable stop 24.

[0029] An end positioning groove 221 is provided at one end of the fixed stop 22 near the movable stop 24. The lowest point of the end positioning groove 221 corresponds to the lowest point of the rolling groove 251. First, one end of the segmented rebar is placed against the movable stop 24 and located inside the two circumferential clamping blocks 241. Force is applied to the segmented rebar and the movable clamping seat 23 is pushed until the clamping distance between the fixed stop 22 and the movable stop 24 is greater than the length of the segmented rebar. Then, the segmented rebar is placed horizontally on the abutting roller 25. After the force is released, the movable clamping seat 23 returns, and the end of the segmented rebar away from the movable stop 24 is embedded into the end positioning groove 221 to form a double-end clamping and positioning of the segmented rebar. Optimally, a pressure sensor can be set in the end positioning groove 221 to know the exact timing when the end of the segmented rebar abuts in the end positioning groove 221, and the obtained value is more accurate. It can be assumed that the length of the segmented rebar is equal to the sum of the initial distance between the fixed stop 22 and the moving stop 24 and the moving distance of the moving stop 24, thus calculating the length of the segmented rebar. More optimally, a protective cover 13 is provided on the upper end of the testing platform 10 near the moving stop 24. The protective cover 13 is used to protect the testing environment, and a moving distance detection sensor 14 is provided in the protective cover 13. This moving distance detection sensor 14, in conjunction with the detection point 15 set on the moving stop 24, automatically calculates the length of the segmented rebar.

[0030] In this embodiment, the length detection component 20 is disposed inside the detection platform 10, improving the overall structural compactness. The ends of the fixed stop 22, the movable stop 24, and the abutment roller 25 protrude from the upper end of the detection platform 10, allowing the segmented rebar to be stored above the detection platform 10 for easy handling during rebar testing. The detection platform 10 is provided with a clearance slot 11 for the abutment roller 25 to slide through. The clearance slot 11 limits the axial movement distance of the abutment roller 25 on the movable stop 24, ensuring that the initial distance between the fixed stop 22 and the movable stop 24 is consistent, and preventing the movable stop 24 from axially sliding off.

[0031] The weighing assembly 30 includes a mounting block 31 disposed at the bottom of the length detection assembly 20. The mounting block 31 facilitates component installation and serves as the bottom mounting and integration of the length detection assembly 20. A fixed clamping seat 21 is fixedly disposed on the mounting block 31, and a movable clamping seat 23 is slidably disposed on the mounting block 31. Specifically, the fixed clamping seat 21 is fixedly connected to the mounting block 31 by threads. The mounting block 31 is provided with an axially arranged sliding groove 311, and the bottom of the movable clamping seat 23 is provided with a sliding protrusion 242 embedded in the sliding groove 311, increasing the sliding stability of the movable clamping seat 23.

[0032] A weighing sensor 32 is provided at the bottom of the mounting block 31. The weighing sensor 32 obtains the weight of the segmented rebar by measuring the difference before and after placement, and calculates the weight deviation of the rebar by combining the rebar length to determine whether the segmented rebar meets the standard. In this embodiment, the length detection component 20 is set at the upper end of the weighing component 30 and does not interfere with other components, avoiding the rebar clamping operation that causes weight detection errors and improving detection accuracy.

[0033] In this embodiment, the detection platform 10 is also equipped with a total weighing pan 12, which weighs all the segmented steel bars to obtain the total value, making it easier to calculate the average value and reduce the error caused by multiple values.

[0034] In other embodiments, please refer to Figure 4 The length detection component 20 has at least two length detection components 20 spaced apart, and each length detection component 20 has a weighing component 30 at its bottom, which can simultaneously detect multiple segments of steel bars, thus improving detection efficiency.

[0035] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
